Have you seen any of the Richard Holdener videos on the old YouTube about this motor ? he was a tech editor for hot rod / motortrend and has done loads of vids covering stock ls turbos etc. playlist below from youtube for like 30vids going through a ton of options on the L67 3.8v6, he even built a twin charged one at some point. Made around 600hp at the crank with a gt45 Yeah been watching his stuff, I was keen for ages to run twin charged but tuning it myself would of been a nightmare, so I got rid of the blower and just bought a decent quality turbo its not a garrett but its decent and the brand has an excellent reputation on turbo LS stuff. I'm currently at a crossroad considering doing a rebore fitting new pistons and opening the ring gaps up. Quote Link to comment Share on other sites More sharing options...
Muncie Posted June 25, 2022 Author Share Posted June 25, 2022 I pulled the heads off a while back on the l67 have come to conclusion..... its fucked heads are full of cracks and bores are scratched to shit looks like someone pushed on with a skid when it was clearly starting to seize. I'm tossing up throwing a set of good rods and forged pistons at the bottom end some ecotec heads as I don't need the injectors in the ports anymore. Or.......... fitting a honda k24 and not wasting my money on the buick the turbo ive bought would be excellent. 4 Quote Link to comment Share on other sites More sharing options...
Muncie Posted June 25, 2022 Author Share Posted June 25, 2022 The poor neglected thing hasn't had a tank of gas for 6 months wof ran out march. Will drive it around and get the fuel tank emptied get the new fuel pump fitted and think more about an engine swap everything ive bought so far bar the head gaskets will work well on another engine. Hmm what would the purists think of this combo. Just spitballing but would give me everything I want. 3 1 Quote Link to comment Share on other sites More sharing options...
GARDRB Posted June 25, 2022 Share Posted June 25, 2022 It's cool and all, but what would it be like off boost? Quote Link to comment Share on other sites More sharing options...

Probably no worse than an Accord a high stall converter would liven it up. Have had a Type S CL7 Accord a few years back stock it was awesome. Ive gotta remember I'm 40+ now so I'll 90% of the time just be cruising around so peaky kinda suits my needs lazy normal driving and on boost like a bottle rocket would work.

mjrstar Posted June 25, 2022 Share Posted June 25, 2022 OK, normally I'd say k swap is cool, but I think we all know turbo Barra is the answer here.. 1 3 Quote Link to comment Share on other sites More sharing options...

I don't understand, you haven't driven it for months and you are worried about the price of petrol? If you want an economy car buy a Yaris. 3 Quote Link to comment Share on other sites More sharing options...

The big Ford Territory SUV with the Non turbo Barra do like 10.2L per 100km for the 2016 model Quote Link to comment Share on other sites More sharing options...

If you want an economy car buy a Yaris. Engine has so much endfloat the crank angle sensor sometimes struggles to find a signal if I brake too hard. I drive it but nowhere getting out and booting the harmonic balancer back in would cause issues/road rage. Quote Link to comment Share on other sites More sharing options...
Muncie Posted June 26, 2022 Author Share Posted June 26, 2022 Barra is a fucking fantastic engine but it is huge and capable of making more power than my licence can handle, And there is already a Barradore on the forum that's going to be way more epic than I could hope to build. If I can build something that makes good reliable power that doesn't destroy gearboxes and diffs that would be ace. 1 1 Quote Link to comment Share on other sites More sharing options...

Roman Posted June 27, 2022 Share Posted June 27, 2022 How much do these weigh? Find this information for me, and I'll send you back some dataz on predictions for how each version of the car will run With an NA K24, turbo K24, NA 1NZ, turbo 1NZ 5 Quote Link to comment Share on other sites More sharing options...
Roman Posted June 27, 2022 Share Posted June 27, 2022 If you're planning on using the 4 speed auto it's going to be pretty punishing with that 1st to 2nd gear gap. Also the final drive ratio in the 3.something is going to reaaaalllllyyy kill a smaller motor. Are there any options in the high 3 or low 4 to 1 region for final drive?

Stu Posted June 27, 2022 Share Posted June 27, 2022 I love how the first sniff of a 1nz conversion and DaveScience is in there with the maths. I heartedly approve. #1nztheworld #morerevs 5 3 Quote Link to comment Share on other sites More sharing options...
Muncie Posted June 27, 2022 Author Share Posted June 27, 2022 @Roman was joking about a 1nz swap.... I'd definitely do new crown wheel and pinion anyway whatever engine goes in as that was always on cards easily available new and fairly cheap. Would give any transmission a go if it bolted up fairly easily. If the 6 stays in I'll keep the 4 speed just because it works. Hmm For shits and giggles though give me the 1nz numbers for "educational purposes" GM 4L60E 4-speed Automatic Transmission First: 3.06 Second: 1.63 Third: 1.00 Fourth: 0.70 Final drive currently 3.08 could be anything in future. Curb weight 1522kg Sedan Wagon One Tonner Wheelbase (mm): 2788 2938 3200 Front track (mm): 1569 1569 1569 Rear track (mm): 1587 1587 1597 Overall length (mm): 4891 5046 5230 Overall width (mirrors) (mm): 1842 1847 2047 Overall height (mm): 1450 1545 1507 Ground Clearance (mm): 150 153 132 Wheels and tyres Are 245/40/19 Coefficient of drag 0.319 Quote Link to comment Share on other sites More sharing options...
Roman Posted June 27, 2022 Share Posted June 27, 2022 Yeah your car is literally twice as heavy as anything that suits a 1.5 litre engine hahaha. But cos it's a laugh, here we are. Alright so this is all of the above data, no weights changed but just engines swapped. Still auto trans and a 3.3 final drive. NA 1NZFE, since this is the least suitable option I'm assuming it's doorty so 160hp @ 8000rpm with 9000 limiter. Turbo 1NZFE 300hp @ 8000, 9000rpm limit NA K24A is the best standard power version, 204hp 7600 limiter Turbo K24A is 300hp @ 7000rpm 7600 limiter If you want to try any of these numbers a bit different, let me know 2 Quote Link to comment Share on other sites More sharing options...
